BACKGROUND ART

Various applications have been developed according to the development of electronic devices. In recent years, an application has been developed in which a plurality of users can participate together through an interaction between electronic devices.

However, in order for a plurality of users to participate through such an application, the corresponding application must be installed in each electronic device for each user. In addition, the development of applications suitable for the installed operating system for each electronic device and the management of each application developed for each operating system should be continuously maintained. Accordingly, there is a problem that not only an additional cost is incurred in developing an application for each operating system with respect to one application, but also an increase in cost due to maintenance for an application developed for each operating system occurs.

Meanwhile, in the conventional method of providing a multi-UI service among the plurality of electronic devices, the service merely transmits the previously stored contents from the main device to the target device through the mirroring method.

The display 120 may display an execution screen of an executed application according to a user command. In addition, the display 120 may display image content received from an external source such as a content server (not shown) and image processed by the control unit 130. The display 120 may be implemented as a liquid crystal display (LCD), an organic light emitting diode (OLED), or a plasma display panel (PDP). If the input unit 150 to be described later is implemented as a touch pad, the display 120 may be implemented as a touch screen having a mutual layer structure together with the input unit 150, which is a touch pad.

The control unit 130 controls the operation of each of the components constituting the display device 100. In particular, the control unit 130 extracts source information related to an area to be transmitted to the peripheral device 200 among the source information stored in the storage unit 160 in relation to a plurality of areas constituting an execution screen of the application. In accordance with such a control command, the communication unit 110 can transmit to the peripheral device 220 the source information pre-extracted by the peripheral device 220. Here, the peripheral device 200 may be a device which is in proximity to the display device 100 or selected according to a user command from among the plurality of peripheral devices 200 communicable with the display device 100. Accordingly, such peripheral device 200 can display an execution screen or information corresponding to a specific area among a plurality of areas constituting an execution screen of the application, based on the source information received from the display device 100.

The sensor 140 may be a proximity sensor that senses whether at least one of the plurality of peripheral devices 200 is in proximity to the peripheral device 100. The sensor 140 may be formed on one side of the display device 100 or on each side thereof.

Further, the storage unit 160 may store an operating system program for controlling the operation of the display device 100. Here, the operating program may be a program that is read and compiled in the storage unit 160 to operate each configuration of the display device 100 when the display device 100 is turned on. The storage unit 160 may be a ROM, a RAM or a memory card (e.g., an SD card or a memory stick) detachably mountable to the display device 100, a nonvolatile memory, a volatile memory, a hard disk drive (HDD) or a solid state drive (SSD).

As illustrated in FIG. 3, the display device 100 may further include a receiver 170, a signal processor 180, and an audio output unit 190.

The receiver 170 may include an IR receiver (not shown) receiving a user command transmitted from a remote control device (not shown) for controlling the operation of the display device 100. Specifically, the remote control device (not shown) may transmit a user command, such as a function setting of the display device 100, to the display device 100 through a control signal such as an IR signal or an RF signal. Accordingly, the receiver 170 can receive a user command such as a function setting of the display device 100 based on a control signal received through a remote control device (not shown) through an IR receiver (not shown). In addition, the receiver 170 may include a tuner unit (not shown) for receiving a broadcast signal of a broadcast channel selected by a user from a plurality of image contents provided from a broadcast server (not shown). In this case, when the channel tuning command is inputted through the remote control unit (not shown), the receiver 170 may tune a channel corresponding to the channel selection command received from the remote control unit (not shown) through the tuner unit and receive the broadcast signal through the tuned channel.

The signal processing unit 180 processes the data received from the terminal device including the plurality of peripheral devices 200 through a broadcast signal of the broadcast channel received through the receiver 170 or the communication unit 110. In addition, the signal processing unit 180 may process the application-related contents executed in accordance with the user's command in a displayable form through the display 120.

The audio output unit 190 may output signal-processed audio data via speaker through the signal processing unit 180, and the display 120 may display the signal-processed video data on a screen through the signal processing unit 180.

As described above, when the peripheral device 200 adjacent to the display device 100 is detected through the sensor 140, or the peripheral device 200 corresponding to the user command input through the input unit 150 is selected, the control unit 130 can extract source information related to an area to be transmitted to the peripheral device 200 among a plurality of areas constituting an execution screen of the application, based on the following embodiment. Here, the source information may include at least one of an execution code and a resource for execution of an area to be transmitted to the peripheral device 200 among a plurality of areas constituting an execution screen of the application.

When the peripheral device 200 adjacent to the display device 100 is detected or selected, the control unit 130 may extract predetermined source information relating to an area to be transmitted to the peripheral device 200 from among a plurality of areas constituting an execution screen of an application.

According to another embodiment, when the peripheral device 200 adjacent to the display device 100 is detected or selected, the control unit 130 may analyze an execution code for executing an area to be transmitted to the peripheral device 200, from among a plurality of areas constituting an execution screen of an application, and extract source information relating to the area.

FIGS. 4A and 4B are exemplary diagrams which extract source information relating to an area to be transmitted to a peripheral device from among a plurality of areas constituting an execution screen of an application according to an exemplary embodiment.

As shown in FIG. 4A, the display device 100 may display an execution screen 410 of an application divided into a plurality of areas according to a user command. The execution screen 410 of such an application can be divided into a plurality of areas, and each area has a hierarchical structure as shown in FIG. 4B. Specifically, each of the plurality of areas constituting the application execution screen 410 may be hierarchically configured with an execution code for executing each area and a resource associated with each execution code.

For example, as shown in FIG. 4A, the first area 411 of the plurality of areas constituting the application execution screen 410 may be located adjacent to the display device 100, or may be determined as an area to be executed in the selected peripheral device 200 according to a user command.

In this case, as shown in FIG. 4B, the control unit 130 performs static/dynamic analysis with respect to an execution code corresponding to the first area 411, from among a plurality of areas, from an execution program to execute the execution screen 420 of the application. If the resource related to the execution code corresponding to the first region 411 is extracted based on the analyzed result, the control unit 130 may analyze the first area 411, an execution code corresponding to the first area 411, and a relationship with the resource extracted from the execution code, to extract source information 411′ relating to the first area 411.

When the source information 411′ for the first area 411 is extracted, the control unit 130 transmits the source information 411′ extracted in relation to the first area 411 to the peripheral device 200. Accordingly, the peripheral device 200 can display the information of the first area 411 based on the source information 411′ received from the display device 100.

The control unit 130 may determine an area to be transmitted to at least one peripheral device 200 from among a plurality of areas constituting an execution screen of an application based on the exemplary embodiment as shown below.

If the peripheral device 200 is detected to be proximate to the display device 100 through the at least one sensor 140, the control unit 130 may detect a position where the peripheral device 200 is proximate based on sensing information sensed from at least one sensor 140.

The control unit 130 then extracts the source information of the first area related to the position where the peripheral device 200 is adjacent to the plurality of areas constituting the application execution screen and controls the communication unit 110 to transmit the source information to the peripheral device 200 adjacent to the display device 100. Accordingly, the communication unit 110 transmits the source information of the first area to the peripheral device 200 adjacent to the display device 100. The peripheral device 200 can generate an execution screen or information related to the first area based on the source information received from the display device 100 and display it on the screen.

According to another embodiment, when the peripheral device 200 is detected as being proximate to the display device 100 through the at least one sensor 140, the control unit 130 may request to the peripheral device 200 which is proximate to the display device 100 based on the detection information sensed through the at least one sensor 140. Accordingly, when the device information is received from the peripheral device 200 adjacent to the display device 100, the control unit 130 controls the plurality of areas constituting the execution screen of the application based on the acquired device information of the peripheral device 200 and extract source information of the first area executable by the peripheral device 200 adjacent to the display device 100. Here, the device information may be specification information for data processing in the peripheral device 200.

The control unit 130 then controls the communication unit 110 to transmit the extracted source information to the peripheral device 200 adjacent to the display device 100.

Accordingly, the communication unit 110 transmits the source information of the first area to the peripheral device 200 adjacent to the display device 100. Accordingly, the peripheral device 200 can generate an execution screen or information related to the first area based on the source information received from the display device 100 and display it on the screen.

According to another embodiment, when the peripheral device 200 is detected as being proximate to the display device 100 through the at least one sensor 140, the control unit 130 may transmit the device information to the peripheral device 200 which is adjacent to the display device 100 based on sensing information sensed through at least one sensor 140.

Accordingly, when the device information is received from the peripheral device 200 adjacent to the display device 100, the control unit 130 extracts the source information of the first area executable in the peripheral device 200 adjacent to the display device 100 based on the device information of the peripheral device 200 and information of the plurality of areas constituting the execution of the application. Here, the device information may be specification information for data processing in the peripheral device 200.

The control unit 130 then controls the communication unit 110 to transmit the extracted source information to the peripheral device 200 adjacent to the display device 100.

Accordingly, the communication unit 110 transmits the source information of the first area to the peripheral device 200 adjacent to the display device 100. Accordingly, the peripheral device 200 can generate an execution screen or information related to the first area based on the source information received from the display device 100 and display it on the screen.

According to another embodiment, the control unit 130 may analyze a plurality of areas constituting an execution screen of an application being executed and, based on the analysis result and the device information of the peripheral device 200 adjacent to the display device 100, may extract and transmit the source information of at least one area to the peripheral device 200 corresponding to the predetermined condition.

To be specific, if the first area of the plurality of areas constituting the execution screen of the application is an area for receiving a user command or an area for displaying user information, the control unit 130 may determine the first peripheral device 200-1 corresponding to the preset first condition as the device to which the source information of the first area is to be transmitted. For example, the first area among the plurality of areas constituting the execution screen of the application may be an area for receiving a simple user command of the user or displaying the personal information of the user. In this case, the control unit 130 controls the first peripheral device 200-1 of the small terminal such as the smart watch or the first peripheral device 200-1 of the peripheral device 200, which is adjacent to the display device 100, as the device to which the source information is to be transmitted.

As such, when the device to which the source information of the first area is to be transmitted is determined, the control unit 130 extracts the source information of the first area and transmits the extracted source information to the first peripheral device 200-1 and controls the communication unit 110 to transmit the data. Accordingly, the communication unit 110 transmits the source information of the first area to the first peripheral device 200-1 adjacent to the display device 100. Accordingly, the first peripheral device 20-10 may receive a user command related to the first area based on the source information received from the display device 100, or may generate and display a UI screen for providing user information.

On the other hand, if the second area of the plurality of areas constituting the application execution screen is an area for displaying contents, the control unit 130 controls the display unit 100 to display a content corresponding to a predetermined second condition among the peripheral devices 200 adjacent to the display device 100. The second peripheral device 200-2 can be determined as a device to transmit the source information of the second area. For example, the second area among the plurality of areas constituting the execution screen of the application may be an area for providing contents with a large amount of information. In this case, the control unit 130 can determine the second peripheral device 200-2 having a high specification for data processing among the peripheral devices 200 adjacent to the display device 100 as the device to transmit the source information of the second area.

As described above, when a device to transmit the source information of the second area is determined, the control unit 130 extracts the source information of the second area and transmits the extracted source information of the second area to the second peripheral device 200-2 and controls the communication unit 110 to transmit the data. Accordingly, the communication unit 110 transmits the source information of the second area to the second peripheral device 200-2 adjacent to the display device 100. Accordingly, the second peripheral device 20-10 can generate and display a content UI screen related to the second area based on the source information received from the display device 100.

According to another embodiment, the control unit 130 may generate at least one of the plurality of areas constituting the execution screen of the application, based on the user command inputted through the input unit 150. Here, the user command may include a first user command for one of a plurality of areas constituting an execution screen of an executing application, a second user command for a device to transmit source information of the selected area based on the first user command.

That is, when the first user command is inputted through the input unit 150, the control unit 130 extracts source information related to the first region corresponding to the first user command among the plurality of regions constituting the execution screen of the application. If the second user command is input through the input unit 150, the control unit 130 determines whether the first peripheral device 200 corresponding to the second user command among the plurality of peripheral devices 200 capable of communicating with the display device 100-1 to control the communication unit 110 to transmit the extracted source information in association with the first area. Accordingly, the communication unit 110 transmits the source information of the first area to the first peripheral device 200-1 corresponding to the command of the second user.

Therefore, the first peripheral device 200-1 may generate an execution screen or information relating to the first area based on source information received from the display device 100 and display on a screen.

In the present invention, description has been made on the case where the source information of the area corresponding to the first user command is extracted, and then the second user command for the peripheral device 200 to transmit the extracted source information is inputted. However, the input unit 150 can simultaneously receive the first and second user commands.

When the source information related to at least one of the plurality of areas constituting the execution screen of the application being executed is transmitted to at least one peripheral device 200, the execution screen of the application can be edited based on the remaining area excluding the area related to the source information, and the edited execution screen can be displayed.

For example, the application execution screen is divided into first to third areas, and the source information related to the first one of the first to third areas is transmitted to the peripheral device 200 adjacent to the display device 100. In this case, the control unit 130 can reconstruct and display an execution screen for the application based on the second and third areas except for the first area of the first to third areas.

Meanwhile, if it is detected that the execution screen return command is input or the peripheral device 200, to which the source information is transmitted, is not adjacent to the periphery of the display device 100, the control unit 130 may re-edit and display an execution screen of the edited application as an initial execution screen.

As a result of the determination, when a user command is received from the peripheral device 200 that has transmitted the source information, the display device 100 controls the operation of the application being executed based on the user command received from the peripheral device 200 (S1350).

To be specific, the peripheral device 200 which receives source information relating to a specific area from among a plurality of areas constituting an execution screen of an application may display information relating to a part of an area from among a plurality of areas constituting an execution screen of an application based on the received source information. While the information is displayed, when a user command for controlling an application is input, the peripheral device 200 transmits the input user command to the display device 100. Accordingly, the display device 100 may control an operation of an operating application based on the user command received from the peripheral device 200.

FIG. 14 is a second flowchart of a controlling method of a display device according to still another exemplary embodiment.

As shown in FIG. 14, the display device 100 displays an execution screen of an application divided into a plurality of areas (S1410). When the execution screen of the application divided into the plurality of areas is displayed, the display device 100 extracts the source information related to the area to be transmitted to the peripheral device among the plurality of areas constituting the execution screen of the application (S1420). When the source information is extracted, the display device 100 transmits the extracted source information to the peripheral device 200 (S1430). Accordingly, the peripheral device 200 can display information on an area related to the received source information among a plurality of areas constituting an execution screen of the application, based on the source information received from the display device 100.

The operations of steps S1410 to S1430 described above are the same as those of steps S1310 to S1330 of FIG. 13 described above. Therefore, detailed description of the operation of steps S1410 to S1430 will be omitted below.

On the other hand, when the source information extracted in step S1430 is transmitted to the peripheral device 200, the display device 100 edits an execution screen of an application based on a remaining area excluding an area relating to source information transmitted to the peripheral device from among a plurality of areas constituting the execution screen of the application and display the execution screen of the edited application (S1440).

For example, the application execution screen is divided into first to third areas, and the source information related to the first one of the first to third areas is transmitted to the peripheral device 200 adjacent to the display device 100. In this case, the display device 100 can reconstruct and display an execution screen for the application based on the second and third areas except for the first area of the first to third areas.

Meanwhile, when an execution screen return command is input or an event is detected in which the peripheral device 200 transmitting the source information is not close, the display device 100 may re-edit and display the edited execution screen as an initial execution screen of the application.

When an event for transmitting source information related to an area changed to the peripheral device 200 occurs, the display device 100 may re-edit the edited execution screen based on the remaining area except for the changed area among the plurality of areas, and display the execution screen of the re-edited application.

The foregoing exemplary embodiments and advantages are merely exemplary and are not to be construed as limiting the inventive concept. The exemplary embodiments may be readily applied to other types of device or apparatus. Also, the description of the exemplary embodiments is intended to be illustrative, and not to limit the scope of the inventive concept, and many alternatives, modifications, and variations will be apparent to those skilled in the art.
